Care guide at a glance
Otocinclus arnoldi
Description
A tiny suckermouth catfish that grazes soft algae from plant leaves and glass without damaging either. Peaceful, useful and rather more delicate than its reputation suggests.
Feeding
Grazes soft green algae and biofilm. Must be supplemented with algae wafers and blanched courgette once the tank is clean.
Compatibility
Entirely peaceful and suitable for any calm community. Keep in groups of six or more.
Behaviour and personality
Works constantly across leaves, glass and wood, grazing. More active and visible in a group.
Before you buy
Almost always wild-caught and often arrives thin and stressed, so early losses are common. Add only to a mature, established tank with algae present, never a new one, and feed deliberately once the algae is gone.
